REFUCTORED Spring PetClinic Sample Application
see https://github.com/buschmais/spring-petclinic for the forked version of the original

Installing and getting to know the sample application
Hint: Preferable, you use the Git bash command line or any Unix-like shell for these tasks.
For our use case, we take the sample application
petclinic of the Spring Framework to demonstrate the usage of jQAssistant and Neo4j. The creator of jQAssistant already put almost everything in place. This version just adds some bad code to have something to analyze.
The sample application itself is a simple demo for organizing visits of pet owners to vets in a clinic.
Understanding the Spring Petclinic application with a few diagrams

Downloading and running the
petclinic web application
First, we want to download the source code of the application with Git, build it with Maven (using
mvnw) and running the embedded web application server
git clone https://github.com/JavaOnAutobahn/spring-petclinic.git cd spring-petclinic ./mvnw tomcat7:run
You can then access the
petclinic web application with your browser here: http://localhost:9966/petclinic/
This is what it looks like:
To shutdown the server, press
X on the command line.
Running jQAssistant / Neo4j locally
After shuting down the web application server, you can start jQAssistant with this Maven command:
You should see the following on the command line:
You can then access the Neo4j browser frontend with the scanned data here: http://localhost:7474
This is what it should look like after clicking the button in the upper left corner (symbol may differ):
Next, you can click on the various labels in the drawer to explore the scanned software data. You can also use the Neo4j guide for jQAssistant (beta) by executing the following command
or by simply clicking this link: http://localhost:7474/browser?cmd=play&arg=http://guides.neo4j.com/jqassistant. The guide will show you some first steps with jQAssistant/Neo4j.
More information e. g. about the scanned Java code can be found in the documentation of jQAssistant: http://buschmais.github.io/jqassistant/doc/1.3.0/#_java_plugin.
